` IMPROVEMENT IN MOLDlNG-MACHINES.

To all whom it may concern:

4 Be it known that I, CONRAD ScH1LL1Ne,of Pekin, in the county ofTazewell and State of Illinois, have invented 'certain Improvements inMachines for Cutting Moldings, 8vo., of which the following is aspecification, reference being had to the accompanying drawing.

My invention relates to a machine for the purpose of sinking and planingpanels, cutting rosettes, molding, boring, Svc.; and consists in a novelcombination and arrangement of a rotary cutter with gear for operatingthe same and a table for supporting the work, as hereinafter described.

Figure I is a sidey elevation of my machine.

5, and 6 are views of different forms of cutters.

In constructing my machine I arrange on a suitable base two horizontalparallel ways, A, and mount thereon a sliding bed, B, having alongitudinal rack-bar, c, formed on its under side, and between the waysI mount a horizontal shaft, C, provided with a pinion, b, gearing intorack a,

ter the bed may be moved to and fro on the ways. By the side of ways A Imount an upright frame, D, one side of which extends out above the bedB, as shown. In the'upper part of this frame I mount a horizontaldriving-shaft, E, provided with cone-pulleys c and a bevel-wheel, F 5and in the outer side of the frame I mount an upright shaft, G, in suchmanner as to have a little vertical play, and on this shaft mount twobevelwheels, H, in the positions shown, so'that, by raising or loweringthe shaft, one or the other of F.` In this manner the motion of shaft Gmay be reversed at will, as it will be turned in one direction when theupper wheel H is in gear, and in the opposite direction when the lowerwheel is in gear. Each end of shaft GImount in a socket, f, attached toone end of a pivoted lever, g, and the opposite ends of these levers Iconnect to a vertical rod, h,- and the lower end of this rod I connectto a pivoted lever, I, which extends forward under the bed in suchposition that it may be readily grasped by the operator. When the leverI is moved it operates rod h and levers g, and-reverses the motion ofshaft G. On the lower part of shaft G I moimt a large pulley, J, and inthe frame D, above the middle of the bed B, I

belt with pulley J, as shown. VWhen motion is imparted to thedriving-shaftE it isV transmitted through the gearing to shaft G andpulley J, and

thence through the belt to the arbor, the motion4 of which latter maybereversed by moving lever.

I. The arbor K I mount so as to slide vertically y in its bearings, andsupport it by a bar, M, which slides on a fixed rod, fi, and is moved bya Vertical screw, N, so that by turning the screw the bar and the arbormay be raised or lowered as occasion requires. The screw I provide witha hand-Wheel, la, by which to turn it, and to the ame I secure aspring-catch, l, so as to engage with the wheel and prevent the screwfrom being turned by the jar or vibration of the frame. The lower end ofthe arbor K I provide with a socket and set-screw, O, bymeans of whichany desired cutter-head, knife, bit, or other tool may be attachedthereto.

In operating the machine a suitable tool is secured to the arbor, andthe wood laid on the bed B, nand the screw turned to bring the tool downupon the wood, the latter being held stationary or moved upon or withthe table, as may be required, and the motion ofthe cutter beingreversed whenever the g'rain of the wood may render it necessary. Iprovide heads or clamps, for attachment to the arbor, of various formsand sizes, adapted for holding different knives and tools, as requiredon different kinds of workone form being shown attached in Fig. 1, whileanother form is shown detached in Figs. 5 and 6. The knives or cutters Imake of sheet-steel, con# cave on one side, and of any required form oroutline on the edge-three forms, r, s, and t, being shown in Fig. 3,while Fig. 4 represents a vertical section of one of them. WhenV themachine is to be used for sinking rosettes or other circular work of thekind, the bed B is fastened bya clamp, T, as shown in Fig. 1, and thewood secured to the bed by screw-clamps U provided for the purpose, asshown in Fig. 2. A tool or cutter having the desired outline is thenattached to the arbor, the latter set in motion, and the hand-wheelturned until the tool is brought down and has cut to the desired depth.

In sinking elongatedpanels the wood is secured to the bed and a cuttersecured to thearbor at the proper distance to one side of the cen-VPATENT .l Prior..-

ter, and then the cutter broughtdown and the bed moved endwise thenecessary distance. When this is done the cutter forms an elongatedrecess or panel, terminated by sen'iicircular ends. The

cutter may be so shaped as to sink the panel and form a molding aroundthe edges thereof at one similar articles, the bed is clamped fast andtwo.

pins, p, screwed into it a little to one side of the arbor, as shown inFig. 2. The frame is then laid on the bed and pressed edgewise againstthe pins, and kat the same time turned slowlyT around and the cutterbrought down to -fornil the molding. In molding the outside of framesand like articles i a single pin, w, is screwed into' the bed, and theframe drawn around the saine. These pins may also be used as guides whenit is desired tol cut or mold both sides of a piece alike, the articlebeing cut or molded on one side and then turned over so that the pinsbear against the edges of the sunken or molded face, and turned aroundwhile the tool cuts the second face, the pins servr ing to guide thewood so as to 'bring the second face directly opposite the first.

When not required for other purposes, the machine may be used forboring, forming tenons, or tonguing and grooving, by attaching asuitable tool to the arbor.

A machine constructed on my plan is simple, cheap, 'and efficient in itsoperation, and, being adapted to many different kinds of W0rk,wi1l` befound of great service to Wood-workers.

Having thus described my invention, what I claim is- 1. The shaft Gprovided with the two bevel gear-wheels H, mounted 'in the movablebearings f pivoted to the levers g having their opposite ends connectedto the shifting-rod h, substantially as described.

2. The sliding shaft K, in combinatisn with the bar M, screw N,perforated wheell k, and springpawl l, all arranged to operatesubstantially as described. Y

' 3. In combination with the devices last above named, the reciprocatingor slidingV bed B, arranged to operate as set forth.
